Post Anchor Identifier

Provides a unique anchor identifier to each post:

<h3 id="post-<?php the_ID(); ?>"><?php the_title(); ?></h3>

Note: In XHTML, the id attribute must not start with a digit. Since the_ID returns the post ID as numerical data, you should include at least one alphabetical character before using it in an id attribute, as in the example above.
